I have put cat /proc/pid/status instead of /proc/pid/smaps. So I was testing the /proc/pid/status and not the /proc/pid/smaps. Now I am testing with /proc/pid/smaps and the values are showing that the old one is faster than the new one. So I will keep using the old smaps version. Any suggestion??? BR, Mauricio Lin.
